Explain it step by step in chat Make a short video of it

The lines y = 10x − 14 and y = -94 meet at x = -8. The solution of the equation is the x-coordinate of the point where the two sides are equal.

How to work it out

1
The goal is to get x alone. Undo the operations in the opposite order: first the subtraction, then the multiplication.
$10x - 14 = -94$
2
Add 14 to both sides:
$10x - 14 + 14 = -94 + 14 \ \Rightarrow\ 10x = -80$
3
Divide both sides by 10:
$\frac{10x}{10} = \frac{-80}{10} \ \Rightarrow\ x = -8$
4
Check: put x = -8 back into the equation.
$10\cdot(-8) - 14 = -80 - 14 = -94 \checkmark$
